TIRE FOR VEHICLE-WH EELS.

SPECIFICATION forming. part of Letters Patent No.`641,735,datecl1a.r11.iary 23, 1900. Application filed April 19, 1899.Serial No. 713,540. (No model.)

To all whom it may concern,.-

Beit known that I, HENRY W. THEIs, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Tiresfor Vehicle-Wheels; and I do hereby declare that the following is afull, clear, and exact description thereof;

Myinvention has especial reference to tires for bicycle-wheels, but isapplicable to the wheels of other vehicles; and it consists in certainpeculiarities of construction and combination of parts, as will be fullyset forth hereinafter and subsequently claimed.

In the drawings, Figure 1 is a partly-perspective and partly-sectionalview of a tire embodying my presentinvention. Figs. 2 and 3 are detailviews illustrating preferred forms of the intermediate structure of saidtire.

Referring to the drawings, A represents the outer tubular portion, and Bthe inner tubular portion, of a tire, said portions being formed ofrubber or analogous material. In-

terposed between the said portions A and BY are shown concentric layersa b of animal hair (from the tails and manes of horses) and woventogether, as indicated in Figs. 2 and 3. The said concentric layerspreferably overlap at their edges, as shown by the edges c d of theconcentric layer ct and the edges e f of the concentric layer b, andthis overlapping may be to any width desired, so that when this comes inline with What is called the tread of the tire it may serve, by reasonof the increased thicknesses of the layers, as a guard against thepuncture of the tire, besides thus making the tire strongest at thispoint of greatest wear. These layers a b greatly strengthen the tirewithout materially interfering with its elasticity or resiliency.

In the preferred form the hair is woven into a fabric, as shown in Figs.2 and 3, and this may have either single warp and woof threads, as inFig. 2, or double threads, as in Fig. 3, or a greater number of threadsfor either the warp or the Woof, or both, as desired, in any instance.In the manufacture of the tire this woven-hair fabric is coated with arubber s0- lution and as many of the concentric layers employed asdesired between the outer and inner tubular portions A B and then allvulcanized together.

It will be observed that the series of concentric layers of woven-hairfabric are everywhere separated from each other by the interposedcoatings of rubber solutions, so that when all the parts of the tire arevulcanized together each layer of fabric is separated from the neXt oneby a layer of rubber, and thus there is no contact of the layers offabric, the

described overlapping ends being also thus separated, all as clearlyshown in Fig. l.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A tire for vehicle-Wheels comprising an inner and outer tubular portionof rubber, with a series of `interposed concentric layers of wovenanimal hair, having overlapping ends at the tread of the tire, each ofsaid layers and its overlapping ends being everywhere free from contactwith the adjacent layer and ends, and separated therefrom by continuouslayers of rubber, and all vulcanized together, substantially as shownand described.

In testimony that I claim the foregoing I have hereunto set xnyhand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.
